I wish to look at home range overlap using a 3D overlap index (preferably UDOI) and using utilisation distributions generated by brownian bridge movement models.
The adehabitatHR function kerneloverlaphr acts on estUDm objects to calculate overlaps.
Is there a way to �stack� the utilisation distributions calculated from the BBMM function brownian.bridge into a single estUDm object that can then be handled by kerneloverlaphr?
Alternatively, is there another function to measure overlap of a brownian bridge generated utilisation distributions?
Thank you in advance,
## Example code:
data(locations) ## Example dataset
BBMM <- brownian.bridge(x=locations$x, y=locations$y,
locations2 <- locations
locations2$x <-locations2$x + 5000 # To create example overlapping UD
BBMM2 <- brownian.bridge(x=locations2$x, y=locations2$y,
x <- # function to stack the bbmm output as a single estUDm object that can be handled by kerneloverlaphr
